For out of Jerusalem shall go forth a remnant
 The Targum is, 
``the rest of the righteous;''the same as before; who, when the city should be free from the enemy, would go out of it, and return to their former settlements, in the several parts of Judea; a type of those who went out of Jerusalem with the Gospel of Christ, and spread it not only in Judea, but in the Gentile world:
 and they that escape out of Mount Zion;
 the same persons, differently described; some of whom were in the city of Jerusalem, and others in the fort of Zion, but departed from hence when the siege was broke up. The Targum is, 
``and the escaped of them that confirm the law out of Mount Zion;''see ( Isaiah 2:3 ) :
 the zeal of the Lord of hosts shall do this:
 his concern for his own honour and glory, and his great love to his people, shall engage him to perform all that is here promised and foretold. The Targum is, 
``by the word of the Lord of hosts this shall be done.''
